Abstract
The present invention provides an ultra-slim bezel display panel, which includes a plurality of light blocking walls formed on a peripheral area of a TFT substrate and a plurality of light blocking walls and a plurality grooves formed on a peripheral area of the CF substrate, wherein the heights of the light blocking walls and the widths of the grooves are determined by taking an additional jet quantity resulting from precision error of a machine into consideration so that, through calculation, the laid sizes of the light blocking walls and the grooves can be correctly determined to prevent, during coating of PI liquid on the TFT substrate and the CF substrate, the PI liquid coated on an outer circumference of an active area from flowing backward into the active area and thus, improve the mura phenomenon occurring in the circumference of the active area and also, to use the light blocking walls on the inside and the outside of circumferential enclosure sealant to achieve an effect of maintaining a cell thickness of a panel around the circumferential enclosure sealant to further improve the quality of a display panel and increase yield rate. The light blocking walls that are provide…
